RUKO KEB-HSS-Mod.55-16.0mm Annular Cutter, 55mm Depth, 19mm Weldon Shank

Cut a 16.0 mm hole through steel with a 55 mm cutting depth using this RUKO annular cutter. The HSS body with multi-tooth geometry removes less material than a twist drill, so the cut is faster and the hole is cleaner.

Overview

The KEB-HSS-Mod.55-16.0mm is a core drill for magnetic drilling machines and pillar drills. It uses a 19 mm Weldon shank (3/4") for secure tool holding. The cutter is uncoated and re-sharpenable, which extends its service life.

What stands out

• High-speed steel body for wear resistance
• Two cutting edges for balanced chip removal
